What are the outputs of the following commands from the Pi terminal - on the first command output remove your web password:

cat /etc/pihole/setupVars.conf

cat /etc/pihole/pihole-FTL.conf

[Manama2011]

pi@PiHole:~ $ cat /etc/pihole/pihole-FTL.conf
PRIVACYLEVEL=0

Can you show us a screen shot of the IPv6 not resolving hostnames issue?

that is the out out of dig-x

Forum tip - you can copy that output to your clipboard and paste the text into a reply. That makes it easier to read in many cases and also allows text searching/copying.

Have you tried using Pi-Hole as DHCP server?

How do I use Pi-hole's built in DHCP server (and why would I want to)?

Using Your Existing Router For Network-wide Ad Blocking You might not need to use Pi-hole's DHCP server: In many home environments, your router also functions as your DHCP server. In this case, you can often set Pi-hole to be the DNS server for your network clients in the router's DHCP (or LAN) settings page, which allows all of your network clients to block ads simply by connecting to the network. Setting it up this way is also what makes Pi-hole very powerful for network-wide ad blocking. …

No, my USG is the DHCP server, but I will try.

Using Pihole as an DHCP server hasn´t changed anything. Is it possible to activte the ipv6 conditional forwarding?

[deHakkelaar]

Why not.
Just make sure DNS queries dont get looped back to Pi-hole like for example when you configure upstream WAN DNS setting on the router to point to Pi-hole.

The web GUI uses below DNS nameserver(s) to lookup names for IP's:

pi@noads:~ $ cat /etc/resolv.conf
nameserver 127.0.0.1

For example lookup name for my laptop 10.0.0.11:

pi@noads:~ $ host -t ptr 10.0.0.11 127.0.0.1
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases:

11.0.0.10.in-addr.arpa domain name pointer laptop.dehakkelaar.nl.
